PUNCHING-BAG MACHINE.

Specification of Letters Patent.

Patented July 10, 1917.

Application filed June 7, 1915. Serial No. 32,541.

To all w hom it may concern:

it known that I, CHARLES M. WEEKS, a citizen of the United. States of America, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented a new and useful Punching-Bag Machine, of which the following is a speciiication.

My invention relates to improvements in punching bags and mechanism for locking and releasing the same and for registering or indicating the force of the blows struck or received, and resides in certain peculiar mechanism. whereby the punching bag is held in inoperative position until released by a coin and elevated into operative position, and whereby said bag when struck causes to be registered the force of the blow and then resumes its inoperative position, together with such auxiliary and subsidiary parts and members as may be needed in order to render the machine complete and serviceable in all respects, all as hereinafter set forth.

The primary object of my invention is to provide a punching bag machine which, although subject to coin control, enables the bag to be released and positioned normally, so that it can be struck as effectually and naturally as a punching bag which is supported from below in the customary man her and left free and in operative position at all times.

A further object is to provide such a machine with means for indicating the force of the blows which the punching bag receives.

Another object is to produce a machine of this character wherewith the punching bag can be struck once only each time it is released, thus necessitating the insertion of a coin for every blow given said bag.

Still another obj ect is to utilize the force of the blow received by the bag, or the blow struck by the bag itself under the impulse or impetus imparted thereto by the blow received thereby, to withdraw said bag from operative position and relock the parts so that the bag cannot again be used until released with the aid of a' coin.

lVith this machine there is no liability of injury to the fist of the person using the same and striking the bag, because the latter stands free and clear when the blow is delivered and then instantly passes away from the fist which delivered the blow, so that the fist is not in contact with the bag at the time said bag delivers its blow.

My machine is simple in construction and operation, effectual and satisfactory as an exerciser, and withal highly practicable and efiicient.

Other objects and advantages will appear in the course of the following description.

A preferred form or embodiment of the invention, whereby I attain the objects and secure the advantages of the same, is illustrated in the accompanying drawings, and 1 will proceed to describe the inventionwith. reference to said drawings, although it to be understood that the form, construction, arrangement, etc. of the parts in various as pects are not material and may be modified without departure from the spirit of the in vention.

In the drawings, in which like numerals designate like parts throughout the several views, Figure 1 is a side elevation of a ma chine that embodies my invention as aforesaid, one side of the boX or housing being. omitted and he top of the major portion of such housing being broken away in places; Fig. 2, a rear elevation of the upper portion of the indicator mechanism, the back side of that part of the housing that appears in this View being omitted; Fig. 3, a front elevation of the dial and pointer of the machine; Fig. i, an enlarged detail showing parts of the indicator mechanism; Fig. 5, a transverse vertical section through the housing, taken on lines 5-5, looking in the direction of the associated arrow, in Fig. 1; Fig.6, an enlarged detail, in top plan, showing parts of the locking and releasing mechanism; Fig. 7, a view similar to Fig. 5, except that the punching bag is shown in operative position in Fig. 7, while in Fig. 5 said bag is shown in inoperative position, the operating parts being disposed according to the positions of said bag in the two views; Fig. 8, a view generally 1 t Figs. 5 and 7, but illustrating an showing parts of the registering and releasing mechanisms, and taken on lines 99, looking in the direction of the associated arrow, Fig. 1; Fig. 10, an enlarged detail. of the bag support; Fig. 11, an enlarged ediate operatlon', Fig. 9, a detail openinglO to which is detail of the bottom portion of the coin tion by broken lines.

The housing of the machine consists of an oblong case 1 having at the rear end a vertical extension 2. In the top of the case 1, near the front end thereof, is a slot 3 for an upstanding lever 4, and back of this slot and ,out of line with the same is a coin slot I There is a slot 7 in the top of the case 1, near the back end or under the chamber in the. extension 2, for a bell-crank lever 8. The-aforesaid top also has an intermediate fitted atrap-door o rftrap 1 1, such trap havingits front edge hinged at 12 to said top, and opening downward. On the front of the extension 2, at the top, is a dial 13 of any suitable character.

1 The lever. 4 has its base pivoted at 14 to a bracket l5that depends from the top ofthe easel, and said lever extends through and above the slot 3 to present the upper termitop. A cord 16 connects the lever 4, at apoint above the pivot 14, .with the depending arm of the bell-crank lever 8. The other arm of the beIl-crank-leVerB is connected by a cord 17 I I with a. detent 18, which latter forms a part of the indicator mechanism I minal, such slots being full lines in Figs. 6 and 11.

I such brackets being extends upwardly in the extension 2, presently to be described.

A coin chute 19 is located in the case 1 under the slot 6, and is hinged at 20 to the underside of the top of said case in such a manner thatsaid'chute may be swung transversely of said, case. The chute 19 has a central longitudinal opening or slot 21 in the outer side, and a central longitudinal slot 22 in the inner side at the lower terrespectively seen in I A money box 23 may be employed in the case 1, such .box having at the top a mouth-piece 24. The baseof the chute 19 is received in the mouthpiece 24, and the latter must be large enough to pcrmit said-base to swing therein when said chute is operated.

I bracket25 is secured to the front Wall of the case 1 inside, also brackets 26 and 27, arranged in the order named one above the other. A curved arm or cam lever 28 has its base pivoted at 29 to the inner terminal ofthe bracket 25 and therefrom. The bracket extends inwardly and has an opening 30 therein .to receive a thrust bar or plunger 31, such opening being in the same vertical plane with the coin-chute slots 21 and 22. The inner end of the bar 31 is pivoted at 32 to the lever 28, and at the outer end o1 said "bar is a step or lug The lever 28 is provided at the top with a stop pin 34 for which a stop 35 is provided on the inside of the front wall of the case. A spring 36, having one end attached to the aforesaid front wall and the other end to the lever 28, tends to actuate said lever away from the chute 19 and normally retains said lever with its pin34 in contact with the stop 35, and when said lever is thus disposed the step 33 at the outer end of the bar 31 lies across the passage through said chute, so that a coin dropped into said chute comes to rest onsaid step. In the absence of a coin on the step 33, the bar 31, which is supported in and guided by the bracket 26, operates freely in and through the slots 21 and 22, whenever the lever 28 is actuated, but, if a coin be present when said lever is rocked toward the chute 19, said coin is forced against the parts of the chute which form said slot 21 and so swings said chute on the hinge 20 toward the adjacent side of the case, or in the same direction with said lever.

Pivot-ally attached at 37 to the bracket 27 is a lock arm 38. The arm 38 extends inwardly and is provided inner end with a tender 39 that rises from said arm. A hooked member 40 projects from the closed side of the chute 19 and loosely engages the arm 38, so that said chute and arm are connected and moved.

together.

Behind the parts that are supported from thefront wall of the case 1 is a pair of vertical rods or posts 41 set in a base plate 42, on the floor of said case, and a head plate 43, attached to the underside of the top of said case. Arranged to slide up and down on the posts 41 is a carrier for a punching bag 44, such carrier consisting of a pair ol cross-heads 45 rigidly connected by an up right 46. The upright 46 is in thetransverse center of the case, and has mounted at the upper end thereof a support or column 47 for the bag 44. There is an openingigtS in the-top of the case, over the upriglitd-O, into which the column 47 extends and through which it operates. The upper crosshead 45 is provided with a forwardly-extending rod 49, into the path of which the outer and convex edge of the lever 28 extends, and said cross-head has at one end a lug 50, into the path of which the lock arm 38 normally extends. The arm 38 is held in place above the lug 30 by means of a spring 51, which'has one end attached to the front wall of the case and the other end to said arm, and the base of the chute 19 which is then in contact with the side of the mouthpiece 24 that is the more remote from the adjacent side of said case.

A hinge 52 is securely fastened to the top of the upright 46, and has the column 17 bolted thereto as shown at 53 in Fig. 10. The under leaf of the hinge 52 is mounted directly on the upright 46, and the upper leaf of'said hinge receives the column 17. The hinge 52 is arranged with the pivotal. connection at the rear, and the upper leaf of said hinge is made longer than the under leaf and projects forwardly beyond the latter, as shown at54. Attached at one end to the part 5 1- is a chain 55, and this chain extends downwardly from the hinge to and through a pulley-block 56, which is fastened to the base plate 42, thence rearwardly to and tl'irough a pulley-block 57, which is attached to a spring 58, and finally forwardly to said plate, to which latter the other end of said chain is secured. The rear end of the spring 58 is attached to the back end of the case 1, and the pulley-block 57 is attached to the front end ofsaid spring. The spring 58, acting through the chain 55, re tains the hinge 52 closed and the column 17 in vertical position under ordinary conditions, and said spring exerts sufficient force to require a smart blow on the punching bag 44 to overthrow said column and open said hinge against such force. The spring 58 also causes the column 4:7 to assume an erect position .again immediately after the blow has been struck which drives the bag rearwardly and downwardly, such blow being received on the front of said bag, and said column to descend into the case 1.

The column 47 should be resilient and therefore preferably consists of a spiral spring. The object of making the column 17 resilient is two-fold: First, the liveliness of the bag 4A is increased thereby, and, second, the shock incident to the action of the spring 58 in returning the column to erect position is absorbed to a great extent by the column spring, and the strain on the hinge 52 decreased.

The bag 14 is attached at the bottom to the top of the spring column 17 by means of a bolt, as shown at 59 in Fig. 10.

The trap 11 is so located in the top of the case 1 that it receives the bag 44 when the latter is overthrown or thrown down, and said trap opens downwardly on the hinges 12, under the force of the blow delivered to said bag and transmitted by the bag to said trap, to unlock or release the sliding carrler for the column 17 and the bag, and to operate the indicator mechanism, as will presently be explained. The trap 11 is provided on the underside near the back edge with a cross bar 60, and forward of said bar with a wedge block 61 the bottom of which block inclines upwardly i and forwardly from the back-end. The cross bar 60 projects beyond the side edges of the trap 11 to engage the corresponding edges of the opentlie case and lines in Fig. 1,

bearings 67 -67 ing 10 and limit the upward movement of said trap. The trap 11. is normally retained in its closed position by means of a post 62., which rests at the base on the floor of the case 1 and supports on the upper end said trap, the block 61 being in direct contact with the top of said post when the latter is erect. The base of the post 62 is hinged in front at 63 to the floor of the case, so as to enable said post to be tilted forward out of supporting relation to the trap 11. The top of the post 62 is beveled to correspond to the inclined surface of the block 61. A spring 64 extends between the back end of the back side of the post 62 and is for the purpose of retaining said post in its upright supporting relation to the trap 11, and of returning said post to such relation. A chain 65 extends between the front side of the post 62 and the upper cross-head 15, and rocks said post on the hinge 63 forward and from beneath the block 61 when said cross-head is drawn up, as shown by dotted said post being actuated against the resiliency of the spring 6%. \Vhen the aforesaid cross-head descends, the spring 6 1 rocks the post 62 back under the block 61, so that said post closes the trap 11.

if open,and secures the same. The chain 65 is taut at all times.

A rock-shaft66 extends longitudinally of the case 1 and has its ends journaled in at opposite ends of said case. A downwardly-extending rocker-arm 68 is secured to the rock-shaft 66 adjacent to one of the posts A1, and such arm has a hook 69 at the bottom to engage the adjacent end of the lower cross-head 45, when said crosshead is in elevated position, and retain the same with the connected members in such position. A laterally-extending rocker-arm 70 is secured to the rock-shaft 66, and projects beneath a vertical plunger 71 which is under the center of the cross bar 60. The plunger 71 is supported by two lugs 72 which project, one above the other and beneath the bar 60, from a bracket 7 3 that is secured to the underside of the top of the case 1, back of the opening 10. A collar 74 is secured to the plunger 71, under the upper lug 72, to limit the upward move ment of said plunger under the influence of a spring 75 which encircles said plunger between the under lug 72 and said collar. The rocker-arm 70 is normally held in contact -with the bottom end of the plunger 71 by 76 which latter extends 73 and the free end of said rocker-arm. The spring 76 also serves normally to retain the hook 69 against the adjacent post 41 or in the path of the adj a cent end of the lower cross-head 4C5, acting as it does through the rocker-arm 70, the rock-shaft 66 and the rocker-arm 68, so that when said cross-head is raisedrit actuates means of a'spring between the bracket for the column 47 thrustsdown the head 45.

said hook outwardly, said spring then yield in momentarily, passes above the same, and finally comes to rest thereon, The carrier and: the bag 44 is thus position until the trap said bag, when said trap plunger 71, against the respring 7 5,, said plunger free end of the rocker-arm 70, against the resiliency of the spring 76, and said rocker-arm, acting through the medium of the rock-shaft 66, so actuates the rocker-arm 68 as to,- cause the hook 69 to be withdrawn. from beneath the lower cross- The bag carrier is now free to de scend. There must be suflicient space between the upper lug 72- and; the trap 11 or thecross bar 60, whelr said trap is closed, topermit thelatter todeliver the full; force of its blow on, the head of the plunger 71, more especially on. account of the indicator mechanism which: is operated by said plungen, and; which will next be taken up.

VYithin, the extension; 2 is a bracket 77,

retained in elevated 11 is struck by drives down the siliency of the and this'bracket affords bearings for a shaft 78' that extends forward' through the center ofthe dial: 13.an,d has a pointer 79 secured thereon outside of said, dial. The pointer 7 9indiicates or registers on the dial 13 the force of the blow struck the bag 44:. A laterally-extending arm 80 is. mounted loosely on the "shaft 78 within the bracket 77, and this arm is provided on the back side with a. pin. 81. The pin 81 extends undera pin 82 that projects from the shaft 78 behind the arm 80 and parallel therewith, when the parts: arenormally disposed; A toothed Wheel 83 is: secured on the shaft 78' behind the pin 82, and the detent 18 engages with its free end said wheel. The detent 18 is pivoted at one endas indicated at 84, to a bracket 85 that is fastened to the front wall of the extension 2, as is also the bracket'77. A spring 86, having one end attached to the front Wall of the extension and the other end to. the detent 18,v retains said detent in engagement with the serrated wheel 83. Slidingly mounted in two brackets, 87 and 88is-a rod: 89. The bracket 87 is fastened to the rear wall of the case 1 and t'he bracket 88 to the front wall of the extensioni2, and these brackets position the rod 89 under the arm 80. The rod 89 has anenlargement orbarrel 90which normally rests on the bracket 87. A spring 91 is attached at the upper end to a cord 95, which is fastened tothe shaft 78, and at the lower end to the-front wall of the extension, and tends to rotate-said shaft in the di'rectionof the arrow in Fig. 2; The spring 91, therefore, actuates or holds the wheel 83 in looking engagement with. the detent 1-8, on the one hand, and, when said detent is withdrawn from saidwheel, said 'springforces the pin 82- against t1 'epin81 and the arm 80 onto the top of the rod 89, on the other hand. A horizontal operating lever 92 is pivotally connected at 93 with a pair oflugs 94 at the bottom of the brackets 73, and" extends forwardly toand through a slot in the plunger 71 and rearwardly to and through a, slot in the barrel 90, as clearly shown in- Fig. 1-. That portion of the lever 92 that is forward? of the pivot 93 is much. shorter than that portion that is behind said pivot, wherefore a com,- paratively slight movement imparted to the front end of said lever is greatly increased at therear end.

The plunger 71 is driven downwardly with considerable force, by the trapill when struck by the bag 4%, as previously explained, and said; plunger in, its descent forcibly rocks the lever 92 on the pivot 93, carrying the front end of said. lever down and the rear end up. The rear endof the le er 92, thus suddenly and forcibly elevated, actuates the rod- 89- upwardly and thrusts said rod with great force against the arm 80, while in turn imparts, through the medium of the pins 81 and 82, a rotary motion to the shaft 78 in the direction contrary to that indicated by the arrow in Fig. 2', with the result that the pointer 79 is carried around to the right. The shaft 78in rotating winds up the cord 95 and stretches the spring 91 until the force of the latter overcomes the impetus imparted to said shaft by the mechanism which caused it to rotate. The wheel 83 is carried around with the shaft 7 8, its teeth clicking past the detent 18,. until the parts stop, when said detent holds said wheel and prevents said shaft from. being reversedby the force of the spring 91. The pointer 79, which rotates with the shaft 78, is thus left with its point adjacent to the number on the dial 13 which indicates the force of the blow received by the punching bag.

The arrangement of parts is such that the pointer 79 points to the number at the top of the dial 13 normally and before the blow is struck, and to restore said pointer to. this initial position the lever 4 is rocked forward. The lever -31 when rocked forward draws the cord 16- forward with it and thus actuates the bell-crank-lever 8'to draw down the cord 17 and actuate the detent 18, against the resiliency of the spring 86, out of engagement with the wheel 83. This operation releases the shaft 78 tothe action of the spring 91, and said spring rotates the shaft 78 in the reverse direction until the pin 82 comes to rest on the pin 81, it being understood that the arm 80 which carries said pin. 81 is already at rest on top of the rod 89, and that said rod has been permitted to descend into its low position. It should here. be observed that the upward thrust of the rod 89 does not throw the arm v52 is not opened when the rising carrier actuates without inserting the coin.

80 so far that said arm does not immediately settle down again onto said rod, it being the parts actuated by said arm and its pin 81 that receive the greatest impetus, due to the fact that the point of contact between the pins is so much nearer the axis of the shaft than the point of contact between said rod and arm, and the speed imparted through said pins is consequently so very much greater than that received and imparted through the more distant members, even in spite of the spring 91. The spring 91 is comparatively light. The inertness on the part of the shaft 7 8 and the members secured thereto is a factor also in limiting the upward movement of the arm 80. The lever 4 is released, as soon as the pointer 7 9 arrives at initial position, and the spring 86 rocks the detent 18 into contact with the wheel 83" once more, in readiness to hold said wheel the next time it is impelled forward, said lever and the connections between it and said detent readily returning to their former positions or conditions with the detent.

The operation of the machine as a whole is described as follows, it being assumed that the movable parts and members are all initially disposed, and that a coin'96, Figs. 8 and 12, has been dropped through the slot 6 into the chute 19 and been received on the step 33 of the thrust bar 31.

The punching bag 14, which is down on top of the case 1, is firstgrasped and raised from said top, the column 47 coming up through the opening 48. The carrier for the column 17 is elevated with said column, the cross-heads 45 of said carrier sliding on the posts 4:1, and the upper end of the chain 55 is taken along with the hinge 52, thus increasing the tension of the .spring 58. The force of the spring 58 is sufficient to balance the weight of the carrier, so that the hinge the bag 4: 1 is raised. The pin 49 on the upper cross-head 45 of the lever 28 against the resiliency of the spring 36, to-

ward the chute 19, and said chute is swung toward the adjacent side of the case in time to swing the arm 38, against the resiliency of its spring 51, out of the way of the crosshead lug 50. If therewere no coin between the outer end of the bar 31 and the adjacent edges of the slot 22, said bar would simply pass through said slot without disturbing the chute 19 or removing the arm .38 from locking position, 'the upward movement of the bag would be and in that event checked as soon as the lug 50 encountered said arm, which is precisely what occurs when anattempt is made to'raise said bag The bag cannot be'raised into striking position or high enough for any practical purpose without the coin, the limit of upward movement in that case being determined by the distance between the lug 50 and the arm 38 as they.

said lug is on a level with said arm and in said arm and receive the ad acent side of a position to ride past the fender 39 against said lug-see Fig. 8. The fender 39 now bears against the lug 50 and prevents the arm 38 from being swung by the spring 51 into the path of said lug, and so interfering with the descent of the carrier. After the pin 49 passes above the major swell of the lever 28, the spring 36 returns said lever to place in contact with the stop 35, and in so doing causes the bar 31 to be withdrawn from the coin 96, when the latter drops down through the bottom of the chute 19 and the mouth-piece 24: into the box 23.

During the raising of the bag 14. the chain 65 draws the post 62 from beneath the block 61, the trap 11 thus being left supported at the rear end solely by the plunger 71.

When the bag 4 1 is raised to the full height, as best illustrated. in Fig. 7 the rocker-arm hook 69 enters beneath the lower crosshead 45 and the rocker-arm 68 retains the carrier with the column 4:7 in elevated position and said bag in striking position. The bag is now released by the operator and he prepares to strike the same.

The operations which are dependent on the raising of the punching bag, which is done by hand, occur quickly, especially if the bag be raised quickly, and the other op erations take place almost instantaneously,

as will readily be understood.

Having raised the punching bag into striking position, the operator next proceeds to deliver his blow. Under the blow. which the bag 4L4: receives from the fist of the operator, said bag falls or is driven with great force downwardly and rearwardly onto the trap '11, the spring 58 yielding and the hinge 52 opening under the force of the impact of such blow. The spring 58 yields for an instant only and then it contracts suddenly, closes the hinge 52 with a snap, thus causing the column 47 to become erect, and draws down the carrier until the bag 4. 1 is on the top of the case 1 and entirely out of operative position, all with the aid of the chain 55 and the pulley blocks 56 and 57. The impact of the blow struck the trap 11 by the bag brings about the release of the lower cross'head 4:5 from the rockerarm 68, so that the parts can descend, said trap acting through the plunger 77 the rocker-arm 7 O and the rock-shaft 66, and the aforesaid impact also causes the pointer to spin around and register on the dial 13 the force of the blow struck the bag, the man raise the bag, and reset the pointer.

upright position position, a punching bag locate said bag in and out "tion.

'ner in which such registration is accomsprings and 7 6 has already brought about that operation. 7

It is clear from the foregoing that the punching bag, through the medium of the operating mechanism therefor, is both selfretracting and self-locking, and it might also be said that said bag is self-registering, or at -least that the bag automatically registers the force of the blow which itreceives. The only manual operations, aside from the 'punch,-are those required to insert the coin, This last act can be attended to, by rocking the lever 4 forwardly and then releasing it, as soon as the last record has been taken or noted, and in any event should be attended to before the bag-is struck again.
